At my previous workplace we had a mix of bare metal (most services), AWS (one service), Digital Ocean (misc), and GCP (BigQuery), and eventually moved almost entirely onto GCP, retaining just a bit of Digital Ocean stuff.

We found that all of these had significant caveats that required careful planning. We had a few instances of runaway AWS costs due to basically not knowing enough about AWS and we had to be careful to only use the "good" AWS products, Digital Ocean never had runaway costs but they did keep turning off production services because our use-case was not one they were familiar with (dev machines, off-site backups). Bare metal was a minefield, we found we couldn't reliably run Prometheus because it ate SSDs. As for GCP, it did require understanding the pricing and it was possible to shoot yourself in the foot with things, but no more than anything else.

There are going to be gotchas everywhere. Overall we had a great experience with GCP, to the point that the company has remained on GCP post-acquisition by another company who were mostly on Azure.
